Quality Control

Our Sodium Sulfosalicylate is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive testing, including assay, identification, and impurity profile analysis, to meet exacting customer specifications. Certificates of Analysis (COA) documenting purity, physical properties, and safety data are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
